Looks very nice Chris, worth all the hard work. My experience of EFS suspension is that it certainly provides a lot of lift, even on big heavy trucks (as discussed), you should be pleased with the ride when your fully loaded. I can't really comment on the unlanden ride quality as our truck was always loaded, the only variance being whether the water and fuel tanks were full of empty. The EFS certainly was composed, rode well on the tarmac and was not phased by hard off road work in high temperatures.
You deserve a whiskey after that lot!
